STMicroelectronics Bipolar Transistor, 10 A NPN, 50 V, 4-Pin SOT-223

The 2STF1550 and 2STN1550 are NPN transistors manufactured using new “PB-HCD” (Power bipolar high current density) technology. The resulting transistor shows exceptional high gain performances coupled with very low saturation voltage.

• Very low collector-emitter saturation voltage
• Fast switching speed
• High current gain characteristic
• Surface mounting devices in medium power SOT-89 and SOT-223 packages
• Applications
• Emergency lighting
• LED
• Motherboard and hard disk drive
• Mobile equipment
• Battery charger
• Voltage regulation
